1.If 200 volts are put across a 300-loop transformer's primarycoil:
a.What will be the voltage output if the secondary coil had 750loops?
b. What is the power in the secondary coil if the resistance inthis coil is 50 ohms?
c. What is the current drawn in the primary coil?
d. What is the power in the primary coil?
2. A model electric train requires 6 volts to operate. If theprimary coil of its transformer has 240 windings, how many windingsshould the secondary have if the primary is connected to a 120-volthousehold circuit
